Análises energética e econômica da produção de leitões de produtores familiares do Oeste do Paraná

The present study aimed to analyze indicators of energy efficiency and economic production of piglets from family farmers in Paraná. We sought to determine possible differences in energy efficiencies and economic producers who manufactured rations on their property and those who bought rations Cooperative. The sample was obtained by accessibility (six producers who manufactured and six who bought rations) and not probabilistic, and the raw data were transformed into energy and economic units, and processed in electronic spreadsheets. The two production systems of piglets in the nursery phase, family farming, showed negative energy balance, with energy inputs higher than outputs. The two systems of rearing piglets showed no differences in energy efficiency, ie, they were not self-sufficient and needed to import energy sources from other systems. The indicators of economic efficiency of producers who buy rations as those who produce them in their properties were less than unity. Thus, most producers did not generate enough revenue to pay the costs in the short term and lost money.

Qualidade pós-colheita de abacates "hass" mantidos em temperatura ambiente e tratados com diferentes radiações

This study aimed the avocado ‘Hass’ conservation with the use of radiation. We performed two experiments: Experiment I – fruits irradiated with different doses of cobalt-60 gamma irradiation(0,0; 0,2; 0,4; 0,6 e 1,0 kGy); Experiment II – fruit irradiated by electron accelerator in different doses (0,0; 0,48; 0,8; 1,12 e 1,45 MeV), both maintained at room temperature of 21±1 °C and at relative humidity of 79±5 %. Antioxidant capacity, total phenolic compounds, fresh weight loss, and respiration rate evaluation were performed every three days for 12 days. The experimental design was completely randomized with three replicates per treatment. For statistical analysis, the Tukey test at 5% probability was employed. Under the conditions in which the experiments were performed, the results showed that the gamma radiation use retained the fruits for 12 days, regardless the doses applied. The radiation by electron accelerator use also promote the fruits preservation, regardless the doses employed.

Vinhos de mesa varietais de uvas americanas: análises químicas e energética

The Brazilian wine industry has a remarkable characteristic that distinguishes from other markets, while the foreign market only accepts products originating from European varieties (Vitis vinifera), in Brazil, products originating from American varieties (Vitis labrusca and Vitis bourquina) and hybrids are also accepted. Dry and sweet varietal wines from varieties Bordô (dry and sweet), Isabel (sweet) e Máximo (dry) were analyzed, by the following chemical standard analyses: alcohol content; density; total and reduced dry matter; alcohol/reduced dry extract ratio; reducing sugars; total, volatile and fixed acidity; pH; total and free sulfur dioxide; and energy value. All analyzed wines presented results within the parameters set forth by Brazilian law, a positive fact, once they are commercialized. The varietal wine Máximo presented a low content of total and free sulfur dioxide, which may cause future problems with its sanity.
